The development, operation, and accomplishments of the Underground Excavation and Rock Properties Information Center (UERPIC) are outlined. The five-year UERPIC effort culminated in a sophisticated information system designed to store and retrieve the data of underground excavation technology, rock properties, and shock-induced geodynamic phenomena. UERPIC's computerized activities and data tapes are maintained at the Purdue University Computing Center where a linked CDC 6500-6600 is supported by Modcomp II and III computers and other peripheral equipment. Documents accepted as data sources for UERPIC's files are derived from the worldwide geotechnical literature. Literature search activities are supplemented periodically by profiled data tapes generated for UERPIC by over 10 foreign and domestic abstracting services. The data bank structure of UERPIC is divided into the three major interrelated components. TUNEX and ROCKP are the most developed and comprehensive. These files dissect the appropriate literature into machine-readable data sets. The type of information that can be extracted from the literature and stored in retrievable form is listed. TUNEX records information pertinent to underground excavation and research technology. DYNEF maintains data on shock-induced geodynamic phenomena. ROCKP subdivides into the following files: rock mechanical properties, rock thermophysical properties, and rock electrical and magnetic properties.
